Capacitor coupled output amplifiers | Audiokarma Home Audio
The function of the output coupling capacitors is to keep the DC voltage from reaching the speaker. This is very common for solid state amplifiers that use a single supply rail for the output stage. The capacitance is high enough to couple all the audio frequencies to the loudspeaker. A smaller value capacitor would limit the low frequencies.

Phase Coupling
X10 does not recommend coupling phases with just a capacitor. Installing a Wired-In Coupler Separate Box. When installing a wired-in phase coupler (a passive coupler, coupler-repeater or a firewall), it is important to remember that the electrical code in most jurisdictions doesn''t permit devices inside the electrical panel.
New Caps
For coupling applications this would mean orienting the capacitor so that the outer foil connects to the "incoming signal" and the inner foil to the "output" side of the circuit. If you look at the cover photo of an original Dynaco ST-70 manual, you will see that Dynaco oriented the caps this way.

6 FAQs about [When installing the coupling capacitor]
How does a coupling capacitor work?
Specifically, coupling capacitors can accurately transmit AC signals from one part of the circuit to another, which is like building a bridge exclusively for AC signals in the circuit. At the same time, it has the ability to block DC signals, which are like being blocked by this “checkpoint” and cannot pass through.
Why is a coupling capacitor used in AC circuits?
A coupling capacitor is used in AC circuits as it allows alternating current to pass through but not the DC current. In some applications, the main purpose of the coupling capacitor is to completely block the DC signal and only allow the AC signal to pass. This is quite common in circuits where DC is the main source of power.
Can a coupling capacitor transmit AC signals?
In essence, they can achieve selective transmission of signals. Specifically, coupling capacitors can accurately transmit AC signals from one part of the circuit to another, which is like building a bridge exclusively for AC signals in the circuit.
Why are coupling capacitors preferred in digital circuits?
Hence coupling capacitors are preferred in analog circuits. In the case of decoupling capacitors, these are preferred in digital circuits. The coupling capacitor, generally only allows the AC signal to be transmitted from one circuit to another. Let us see how it happens.
Can a capacitor be used as a coupling or blocking capacitor?
A capacitor can function as a coupling capacitor, as it helps transfer energy to an output circuit while blocking DC signals from interfering with AC signals within an input circuit. Capacitors can be classified into two groups, namely:
What is the difference between a coupling capacitor and a decoupling capacitor?
While coupling capacitors pass through AC signals to output, do pretty much the opposite; decoupling capacitors shunt AC signals to ground and passes through the DC signal in a circuit. Decoupling capacitors are designed to purify DC signals of AC noise.
